The category of mood§ 73. The meaning of this category is the attitude of the speaker or writer towards the content of the sentence, whether the speaker considers the action real, unreal, desirable, necessary, etc. It is expressed in the form of the verb. There are three moods in English - the indicative mood, the imperative mood and the subjunctive mood. The indicative mood § 74. The indicative mood form shows that what is said must be regarded as a fact, as something which has occurred or is occurring at the moment of speaking or will occur in the future. It may denote actions with different time-reference and different aspective characteristics. Therefore the indicative mood has a wide variety of tense and aspect forms in the active and passive voice. The imperative mood § 75. The imperative mood expresses a command or a request to perform an action addressed to somebody, but not the action itself. As it does not actually denote an action as a real act, it has no tense category; the unfulfilled action always refers to the future. Aspect distinctions and voice distinctions are not characteristic of the imperative mood, although forms such as, be writing, be warned sometimes occur. The imperative mood form coincides with the plain stem of the verb, for example: Come here! Sit down. The negative form is built by means of the auxiliary do + the negative particle not (the contracted form is don’t). This form is always addressed to the second person. Do not take it away. Don’t worry about the child. Don’t be a fool. Note: Do is also used in commands or requests to make them more emphatic: Do come and stay with us. Do be quiet. In commands and requests addressed to a first or third person (or persons) the analytical form let + infinitive without the particle to is used. The verb let functions as an auxiliary, and it partly loses its lexical meaning. The person addressed is expressed by the personal pronoun in the objective case. Let us go together. Let him finish his dinner first. Let Andrew do it himself. In negative sentences the analytical forms take the particle not without an auxiliary. Let us not argue on the matter. Let him not overestimate his chances. Let her not go any further. Note: In sentences like Don’t let him go the negation refers to the verb let, which in this case fully retains its original meaning of permission. The analytical forms differ in meaning from the synthetic forms, because their meaning is closely connected with the meaning of the pronoun included in the form. Thus let us do smth denotes an invitation to a joint action, not an order or a request. Let him do it retains to some extent the meaning of permission. In the form let me (let me do it) the first person singular does not convey any imperative meaning and should not therefore be regarded as the imperative. It conveys the meaning of I am eager to do it, allow me to do it. The imperative mood form can’t be used in questions. The subjunctive mood § 76. The subjunctive mood is the category of the verb which is used to express non-facts: unreal or hypothetical actions or states. A hypothetical action or state may be viewed upon as desired, necessary, possible, supposed, imaginary, or contradicting reality. Different forms of the verb are employed for this purpose. The synthetic forms § 77. In Old English the subjunctive mood was expressed by a special system of forms with a special set of inflections, different from those of the indicative. In the course of time, however, most of the inflections were lost, and the difference between the forms of the subjunctive and those of the indicative has almost disappeared. In Modern English there remain only two synthetic forms of the old regular system of the subjunctive, which differ from the forms of the indicative. Although their meaning and use have changed considerably, they are often called by their old names: the present subjunctive and the past subjunctive. I. The present subjunctive coincides with the plain verb stem (be, go, see) for all persons in both the singular and the plural. It denotes a hypothetical action referring to the present or future. Of these surviving forms only be is always distinct from the indicative forms and is therefore rather current. 
He required that all be kept secret. Other verbs are rarely used in the subjunctive in informal style, because their subjunctive forms coincide with the indicative except in the 3rd person singular. They are confined mainly to formal style and formulaic expressions - prayers, wishes, which should be memorized as wholes. It is natural enough the enemy resent it. Heaven forbid! The devil take him! Long live freedom! God save the king! II. The past subjunctive is even more restricted in its usage; it exists in Modern English only in the form were, which is used for all persons both in the singular and plural. It refers the hypothetical action to the present or future and shows that it contradicts reality. If I were you! If you were there! If it were true! The modem tendency, however, is to use was and were in accordance with the rules of agreement (he was, they were). The non-factual forms of the tenses § 78. Owing to the same process of the obliteration of distinctions between the old subjunctive and the indicative the same forms have come to be used for both purposes in Modern English. To differentiate those used to express hypothetical actions or states (non-facts) from tenses in the indicative they will be called non-factual forms of the tenses. The non-factual past indefinite and past continuous are used to denote hypothetical actions in the present or future; the non-factual past perfect and past perfect continuous denote hypothetical actions in the past. These two pairs of forms differ not only in their time-reference but also in their degree of improbability: If I had only known expresses greater improbability than If I only knew because it refers to a time which has already passed. In Russian this difference is not reflected in the form of the verb. The wide use of the non-factual past indefinite (If I knew, if he came...) probably accounts for the strong tendency in Modern English to substitute was for the past subjunctive form were, at least in less formal style. This tendency makes the system of subjunctive mood forms more similar and comparable to the system of indicative mood forms: if I knew..., if I was (instead of were), I wish I knew..., I wish I was (instead of were). On the other hand, were is often used instead of was in the non-factual past continuous. He smiled as if he were enjoying the situation. The analytical forms § 79. Most of the later formations are analytical, built by means of the auxiliaries which developed from the modal verbs should and would, plus any form of the infinitive. The auxiliaries, generally called mood auxiliaries, have lost their lexical meaning and are used in accordance with strict rules in certain patterns of sentences or clauses. In cases where should and would retain their original modal meaning or their use is not determined by any strict rules, they should be regarded as modal verbs, forming a compound verbal (or nominal) modal predicate. You should be more palient with the child. Still, some modal verbs are regularly used to denote hypothetical actions in certain syntactic patterns - may/might + infinitive, can/could + infinitive, but to a certain degree retain their original meaning. These will be regarded as quasi-subjunctive forms. However much you may argue, he will do as he pleases (expresses possibility). I wish I could help you (expresses ability). If you would agree to visit my uncle, ... (expresses wish). Analytic forms may be divided into three groups, according to their use and function. I. The forms should + infinitive (for the first person singular and plural) and would + infinitive (for the other persons). This system coincides in form with the future in the past. These forms may be used either in a simple sentence or in the main clause. There is a strong tendency in Modern English to use would for all persons, in the same way as will is used instead of shall in the indicative mood. Another tendency is to use the contracted form of would –‘d for all person in informal style. (Compare this usage with that of the contracted form ‘ll in the indicative.) These forms denote hypothetical actions, either imagined as resulting from hypothetical conditions, or else presented as a real possibility. I would not praise the boy so much. Would you help me if I need your help? He would smoke too much if I didn’t stop him now and again. II. The form would + infinitive for all persons, both singular and plural. This form is highly specialised in meaning; it expresses a desirable action in the future. It may be used both in simple and complex sentences. Let us invite him. He would gladly accept the invitation. I wish you would go there too. III. The form should + infinitive for all persons. This form stands apart in the system of the verb, as contrary to the general tendency to use either two forms - should and would, or else to use one form - would for all persons. The meaning of the form is rather broad - it depends on the context. It is important that all the students should be informed about it. It is strange that we should have met in the same place. It can easily be seen that most of the forms used to express hypothetical actions are homonymous with the indicative mood forms, either with tense forms or with free combinations of modal verbs with the infinitive. Hence most forms are recognizable as subjunctive only under certain conditions: 1) when they are used in certain sentence or clause patterns. We shall regard such cases as structurally determined use of the subjunctive mood; 2) when their use is determined by the lexical meaning of the verb or conjunction (see below examples with the verb wish and the conjunction lest). 3) in some set expressions (formulaic utterances) which have to be learned as wholes and in which no element of the structure can be omitted or replaced. We shall regard these cases as the traditional use of the forms. The first two conditions very often overlap. The subjunctive mood and the tense category § 80. The category of tense in the subjunctive mood is different from that in the indicative mood: unlike the indicative mood system in which there are three distinct time-spheres (past, present, future), time-reference in the subjunctive mood is closely connected with the idea of unreality and is based on the following opposition in meaning:
The difference in meaning is expressed by means of the following contrasting forms: 1) The common or continuous non-perfect infinitive as contrasted with the perfect common or continuous infinitive in the analytical forms with should, would, and quasi-subjunctive forms with may (might).
2) The forms of the non-factual past indefinite and past continuous contrast with the forms of the non-factual past perfect and past perfect continuous in time reference:
In case these forms are used in subordinate clauses (as is usually the case) their time-reference is always relative. The non-factual past indefinite and past continuous indicate that the hypothetical action is regarded as simultaneous with the action expressed in the principal clause; the non-factual past perfect and past perfect continuous indicate actions prior to the action expressed in the principal clause. We did things and talked to the people as if we were walking in our sleep. His face was haggard as if he had been working the whole night. The opposition of the non-perfect continuous infinitive and the perfect continuous infinitive is less distinct, as these forms are not so common: an imaginary action is usually presented as devoid of any aspective characteristics. The old synthetic forms (he be, he come, he were) have no corresponding oppositions in time-reference. Structurally determined use of subjunctive mood forms § 81. In Modern English the choice of the subjunctive mood form is determined by the structure of the sentence or clause even more than by the attitude of the speaker or writer to what is said or written. There exist strict rules of the use of the forms in different patterns of sentences and clauses. The subjunctive mood in subject clauses § 82. 1. The use of the subjunctive mood forms in subject clauses in complex sentences of the type It is necessary that you should come. Subject clauses follow the principal clause, which is either formal or has no subject (exclamatory). The predicate of the principal clause expresses some kind of modality, estimate, or some motive for performing the action denoted by the predicate in the subordinate clause. This close connection between the two predicates accounts for the nature of the subordinate clause, which completes, or rather gives meaning to general situation described in the principal clause. Should + infinitive or present subjunctive is generally used in this pattern in the subject clause.
It is sad that you should have heard of it on the day of your wedding. It is a happy coincidence that we should meet here. It shocked him that he should have been so blind. It was suggested that somebody should inform the police. It was more important that he should care for her enough. In American English the present subjunctive is predominant in this sentence pattern: It is sad that you be here. In exclamatory complex sentences: How wonderful that she should have such a feeling for you! What a scandal that Palmer and Antonia should go to the opera together! If the principal clause expresses possibility (it is probable, possible, likely) may (might) + non-perfect infinitive is used, because the action is referred to the future (Возможно, что...; похоже, что...; видимо...) It is likely the weather may change. It is possible the key may be lost. In negative and interrogative sentences, however, should + infinitive is used:
Note: If in sentences introduced by it the reference is made to an existing fact or state of things, the indicative mood may be used in the subordinate clause. It is strange that he behaves like that. Is it possible that he has taken the key? 2. After the principal clause expressing time - it is time, it is high time -the past subjunctive or non-factual forms are used. It is time you went to bed. It is high time he were more serious. It was hight time he had come to a decision. The subjunctive mood in object clauses |
